The mothers on Manhattan’s chic Upper East Side are highly educated, extremely wealthy, and very competitive. They throw themselves and all of their energy and resources into full-time child rearing, turning their kids into the unwitting pawns in a game where success is measured in precocious achievements, jam-packed schedules, and elite private-school pedigrees. Hannah Allen has recently moved to the neighborhood with her New York City–bred investment banker husband and their two-year-old daughter, Violet. She’s immediately inundated by an outpouring of advice from her not-so-well-intentioned new friends and her overbearing, socially conscious mother-in-law, who coach her on matters ranging from where to buy the must-have $300 baby dress to how to get into the only pre-pre-preschool that counts. Despite her better instincts and common sense, Hannah soon finds herself caught up in the competitive whirl of high-stakes mothering.
